Better data array structure in drupal_add_js(.., 'settings')

Issue Summary

drupal_add_js(array('UserTitlesImageURL' => base_path() ."$path/delete.gif"), 'setting');

To make the array keys more unique(per module), it can be good to use:

array('userTitles' => array('imageURL' => base_path() ."$path/delete.gif"))

and access it in JS as: Drupal.settings.userTitles.imageURL

Really minor but couldn't resist. :P
